Show wordsHide wordsMore about this word part:
The prefix in-2 occurs in Latin loanwords and attaches to Latinate bases. The bases of most words prefixed with in-2 are independent adjectives (inadvertent , incognizant ), although the base adjective may no longer be in widespread use (as with incessant ). Exceptions include iniquitous and indignant . -in2 has multiple forms, as the 'n' sound in in-2 assimilates to the initial sound of the base to which it is attached. See the assimilated forms ig-, il-2, im-2, and ir-2.
